Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1, be the structural representation of shape for hat shaped steel, the present embodiment is to cut off shape for hat shaped steel.
As shown in Figure 2-5, a kind of diel for cutting off shaped steel, comprise patrix composition and counterdie composition, described patrix composition comprises cope match-plate pattern 1 and is connected on cope match-plate pattern 1 for cutting off the punch composition of shaped steel 4, described shaped steel is shape for hat shaped steel, described counterdie composition comprises lower bolster 2 and two groups of being connected on lower bolster 2 are symmetrical arranged ground die composition, certain interval is had between described two groups of dies composition, on described lower bolster 2, two groups of die composition arranged outside are made up of adjustable positioning and form with loading bracket, described cope match-plate pattern 1 is slidably connected by guide pillar 3 with lower bolster 2.
As shown in Fig. 4,6 and 7, described punch composition is by punch retainer 5 and cut off punch 6 and form, and described punch retainer 5 is fixedly connected on cope match-plate pattern 1, and described cut-out punch 6 to be fixedly connected on punch retainer 5 and to be placed between two groups of dies compositions; As shown in Fig. 5,8 and 9, described die composition is made up of die block 7 and cut-out die 8, described die block 7 is fixedly connected on lower bolster 2, described cut-out die 8 is fixedly connected in die block 7, described die block 7 and cut-out die 8 are respectively arranged with the groove for placing shape for hat shaped steel, the shape of described groove is mated with shape for hat shaped steel bottom, described cut-out punch 6 bottom both ends of the surface and to cut off die 8 and end face corresponding to cut-out punch 6 be cutting edge portion for cutting off shape for hat shaped steel.
As shown in Figure 6, described cut-out punch 6 bottom cutting edge portion parabolically shape, its both sides, upper end are connected with cut-out punch 6 dual-side by orthodrome.Sharper owing to cutting off punch lower end, side angle is larger, and the cutting edge cutting off punch progressively contacts shape for hat shaped steel, and mould is stressed more even, can avoid the moment stressed destruction to equipment.
As shown in Figure 4, on described cope match-plate pattern 1, cut off the both sides of punch 6 and be provided with stripper 9, described stripper 9 is slidably connected with cope match-plate pattern 1 by screw rod, on described screw rod, between stripper 9 and cope match-plate pattern 1, be socketed with spring 10, and described stripper 9 forms corresponding matching with die.Patrix composition move down carry out punching press blank time, stripper coordinates with die block to be pushed down shape for hat shaped steel both sides, prevents shape for hat shaped steel from occurring movement when being stamped and affects the problem of cutting section quality.
As shown in Figure 10, described loading bracket composition comprises the some backing rolls evenly distributedly 12 being symmetrical arranged ground retainer support 11 and being arranged between two retainer supports 11, and described retainer support 11 is fixedly connected on lower bolster 2 and one end is resisted against die composition end face corresponding with it; As shown in figure 11, described adjustable positioning composition comprises the locating piece 14 being symmetrical arranged ground locating support 13 and being adjustably connected on locating support 13, and described locating support 13 is fixedly connected on lower bolster 2 and one end is resisted against die composition end face corresponding with it.Spacing between described retainer support 11 is less than the Breadth Maximum of shape for hat shaped steel top flange, and the spacing between described locating support 13 is greater than the Breadth Maximum of shape for hat shaped steel top flange.
Operation principle of the present invention: the shaped steel that need cut off is placed on loading bracket composition, driven forward shaped steel is also located by adjustable positioning composition, patrix composition moves down, cut-out punch is utilized to be cut off coordinating of die with cut-out, finished product, waste material rely on gravity to fall into finished product box, ash can separately, driven forward shaped steel location again, circulate above-mentioned work.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
